Ideas for me for Fanime 13

[Guest moohn]

Hello!
I know this is really early to even think about fanime13 but I have never been to fanime (or any anime convention for that matter) and will definitely go this year!  And I know i want to dress up for the convention!  And I'm asking this early to prepare accordingly.  Search for costumes, maybe even make it.
I would really appreciate some ideas that you guys think I could possibly pull off.
The only one I can think I can reasonably pull off is van grants from Tales Of The Abyss.  I really wanna do Asch The Bloody also lol.  waaaaa
Any thoughts of other anime you guys think I might be able to do?
This is the most recent pick of me.  Have hair just barely passing shoulders.  I dont mind wearing wig either lol.  
Thank you!
